A comment on the center for vertical eye movements in the medial prerubral subthalamic region of the monkey considering some of its frontal cortical afferents.
Human clinicopathological studies and experimental studies in monkeys have accumulated evidence that a critical area for vertical eye movements is located in the primate prerubral subthalamic region, but a considerable proliferation of terms applied to the same paramedian structures has impeded progress in the description of its connectivity. Our anterograde horseradish peroxidase (HRP) studies, following HRP gel implants into paraarcuate frontal cortical areas, shed light on the question of its afferents. If one considers the entire spectrum of connectivity of the area as studied by various investigators under different terminologies, it appears that the cell group in question receives convergent inputs from the premotor and prefrontal cerebral cortex, basal ganglia, cerebellum, vestibular complex and paramedian pontine reticular formation.
